Layer Glossary

Layer Type	Description	Layer Preview Image
`3D Layer`	3D layer displays 3D models on map by using latitude and longitude coordinates.
`Arc Layer`	Arc layers are useful for visualizing the distance between two points as well as comparing distances in 3D.
`Cluster Layer`	Cluster layers visualize aggregated data based on a geospatial radius.
`Flow Layer`	Flow layers visualize origin-destination movement patterns between latitude and longitude coordinates.
`Geojson/Polygon Layer`	Polygon layers can display either paths, polygons or points. For example, a path layer can display data like trip routes.
`Grid Layer`	Grid layers are similar to heatmap layers. They show the density of points.
`H3 Layer`	H3 layers visualize spatial data using H3 Hexagonal Hierarchical Spatial Index.
`Heatmap Layer`	Heatmap is a graphical representation of data in which values are represented as colors.
`Hexbin Layer`	Hexbin layers aggregate points into hexagons. The counts can be represented through color and/or height.
`Hex Tile Layer`	Hex Tile layers use Foursquare's proprietary Hex Tile tiling system.
`Icon Layer`	Icon layers are a type of point layer. They allow you to differentiate between points by assigning icons to points based on a field.
`Line Layer`	Line layers are the 2D version of arc layers. Both draw a line between two points to represent distance,but, in a line layer, the drawing lies flat on the map.
`Point Layer`	Point layers draw points for a given event or object based on its latitude and longitude.
`Raster Layer`	Raster layers show aerial photographs, imagery from satellites, or even scanned maps.
`S2 Layer`	To use S2 layers, you need to assign a column containing S2 tokens.
`Trip Layer`	Visualize movement through animations, such as air travel over a period of time
`Vector Layer`	Vector layers use the three basic GIS features to represent real-world features in digital format.
`WMS Layer`	WMS layers render map imagery optimized for the current viewport.
